It appears there is no withdraw process for @ipcc.bsky.social, participation in which is voluntary, free and open to all UN and WMO members. So the Trump administration’s supposed withdraw means less than their June firing of all the staff of the State Dept’s Office of Global Change

After the US admin cancelled the $B Climate + Weather Disaster dataset, @climatecentral.org hired the scientists who ran it and set it back up.

Now the 2025 numbers are in: it's 3rd highest year on record and highest year w/o land-falling hurricanes.

"Because the U.S. entered the UNFCCC with advice and consent of the Senate in 1992, it’s our legal view that it also must be exited using the same process in reciprocation... Letting this lawless move stand could shut the U.S. out of climate diplomacy forever"

We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.

Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.
